90 CURRENT RELEASE NOTES:
92 * Forward binary compatibility is expected of Apache 2.4.x releases, such
93 that no MMN major number changes will occur after 2.4.1. Such changes can
94 only be made in the trunk.
96 * All commits to branches/2.4.x must be reflected in SVN trunk,
97 as well, if they apply. Logical progression is commit to trunk
98 then merge into branches/2.4.x, as applicable.
100 * Current exceptions for RTC for this branch:
104 . non-Unix, single-platform code
106 RELEASE SHOWSTOPPERS:
109 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
110 [ start all new proposals below, under PATCHES PROPOSED. ]
114 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
115 [ New proposals should be added at the end of the list ]
117 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
118 backport keeps syslog logging as part of httpd core and only adds
119 API to allow other modules to be used for error logging.

169 *) http: Don't remove the Content-Length of zero from a HEAD response if
170 it comes from an origin server, module or script. Allow the previous
171 behaviour (for legacy/buggy modules only, not origin) by also backporting
172 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
173 comes for free with the same commit).

178 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
179 ints added at the end of core_server_config, the proposed merge
180 does a minor bump only.

339 2.4.x patch: https://people.apache.org/~minfrin/httpd-mod_alias-expr2.patch
343 PATCHES/ISSUES THAT ARE BEING WORKED
345 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
346 fetching the request body, so to minimize the delay between it is supposed
347 to be alive and the first bytes sent: this is a best effort to prevent the
348 backend from closing because of idle or keepalive timeout in the meantime.
349 Also, handle a new "proxy-flushall" environment variable which allows to
350 flush any forwarded body data immediately. PR 56541+37920.
351 trunk patch: http://svn.apache.org/r1656259
352 http://svn.apache.org/r1656359 (CHANGES entry)
353 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
355 -0: jim: This seems to be a hit to normal performance, to handle an
356 error and/or non-normal condition. The pre-fetch is
357 expensive, and is always done, even before we know that
358 the backend is available to rec' it. I understand the
359 error described, but is the fix actually worth it (plus
360 it seems to allow for a DDoS vector).
361 ylavic: It seems to me that the problem is real since we reuse the
362 connection before prefetching 16K (either controlled by the
363 client, or by an input filter), we currently always prefetch
364 these bytes already. Regarding performance I don't see any
365 difference (more cycles) compared with the current code.
366 However I think I failed to rebuild the header_brigade when
367 the proxy loop is retried (ping), so I need to rework this.
368 Do you think we'd better remove the prefetch, or maybe just
369 make it nonblocking (by default)?
370 jim: Non-blocking seems the best way to handle...
372 PATCHES/ISSUES THAT ARE STALLED
374 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
375 and ProxyMatch section to distinguish between normal workers and workers
376 with regex substitutions in the name. Implement handling of such workers
377 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
378 matched and used for request. PR 43513.
379 trunk patch: http://svn.apache.org/r1609680
380 http://svn.apache.org/r1609688
381 http://svn.apache.org/r1641381
382 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
383 Also added missing r1609688 to the patchset.
384 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
386 -0: covener tried to review this one in Austin with Jeff. Does the added match function
387 really cover a very narrow set of parameters with the way it skips over backreferences?
388 Also, why a new API vs. just setting the field inline?
390 * mod_systemd: New module, for integration with systemd on Linux.

412 * mod_proxy: Ensure network errors detected by the proxy are returned as
413 504 Gateway Timout as opposed to 502 Bad Gateway
414 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
415 2.4.x patch: trunk patch works modulo CHANGES
417 -1: rpluem: This change is still disputed. See
418 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
420 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
421 compiled by the build compiler instead of the host compiler.
422 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

427 fuankg: on hold until we agree for a better and more simple solution ...

430 Moved fixing of shebang to separate target so that it is
431 no longer executed by default and all CGIs remain inactive.

435 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
438 This commit is essentially deciding that an httpd install on
439 Windows now has printenv/testcgi written in 2 more languages.
440 To the extent that the usefulness is that it shows how to make scripts
441 of these types executable by httpd, I believe that the documentation
442 is the proper place to solve that. To the extent that the usefullness
443 is to show how to implement a CGI in these particular languages, I believe
444 that the httpd distribution and documentation in general is not the
445 place for that. Historically these types of scripts have caused problems
446 for downstream vendorsas well as newbies (and sometimes the intersection
447 of those two groups) who don't understand that these are information leaks
448 once they are enabled, and the subtlety of the way they are disabled ("Apache
449 messed up the first line; let me fix that") contributes to that.
450 fuankg notes: I've just added a big warning to all CGI scripts which should now
451 make absolutely clear that these CGIs are for testing purpose only - so those
452 who enable those scripts with inserting the right shebang should be 100% aware
453 of any risks (this should cover your last point).
454 jim: trawick, does the above address your concerns?
455 trawick: to some extent (somebody reading the script gets an idea)
456 Why isn't the configuration requirement documented instead
457 of described indirectly in a sample?
458 Why are these new samples added to the install without three
459 votes? (I didn't veto it; put your name next to the two
460 existing ones and I'll be satisified that enough people
461 considered this addition as an appropriate solution for a
462 real httpd usability problem.)
463 wrowe: I'd agree with trawick, and suggest that these scripts can begin
464 their life somewhere in the manual/ tree. This really seems like
465 the place where /usr/share/httpd/examples/ would be useful, but
466 there isn't an ordinary directory for that. Since we want none
467 of the scripts to function 'out of the box', what about a new
468 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
